Clean channel not working. Still doesn’t with tested good valves in, something else going on, but not too easy to investigate stuff with loads of surface mount and SS shenanigans.
Big heat sink with presumably voltage regulators on, heat right next to the filter caps seems a terrible idea. Strong theme of this amp, sent it off without a fix as it was nothing readily apparent.
Bought dead on ebay, to have a look at. Turned out it was just bunch of dead preamp valve, guy had reloaded it with JJs and they died after estimated 50 hours use.
Front of it, 5150 MKI style, but reverb option.
Random tested parts box valves I stuffed in, the Infinium sorts out the bias for them. Works fine by ear, not sure sticking a probe in won’t interfere with its function, so didn’t.
Inside, the infinium part is the board on the back of the chassis with bunch of push connectors. Small board with ribbon cable is the reverb. Modular inside, would guess lots of stuff in common with other models in the line.
Clsoer shot of the small modular boards, along with showing that the main circuit is pretty normal through hole pcb, not mystical magic that cannot be fixed like is often claimed about these amps. Ribbon cable is data from digital reverb.
Did some videos for Warrior Pope live recording.
This Peavey Artist came in for triage, touring band from Sweden, different electrical regs there so shenanigans inside. Fuse on the bias is a genius plan.
Blown fuse on the board, and this cooked looking cap is prob the issue, but not one I have to hand. Put a new fuse in and wished him luck, apparently it works, will need a proper sorting when they aren’t on tour.
Not sure if linked this before, but I set up a Facebook page for pedal sales. This should be a link to the folder of pedals for sale: https://www.facebook.com/media/set/?set=a.1691321974457138.1073741828.1691292437793425&type=1&l=d5e029728f
Or just look up Tone Wolf Audio on Facebook.
Epiphone Blues Custom guts. Had an intermittent rattle, nothing showed while it was in, nothing loose, possible worn fan, if a tighten down and cleaning grub out the fan hasn’t sorted it, gotta replace it. Some weak pre valves too, cleaned sockets and replaced.
